如何清除Laravel雄辩模型的关系属性？

Question

There are two models

item
image

and there is hasMany relationship between them (item has many images)

I need to delete all images of item, then create new images and pass the item with new images to view.

$item->images()->delete();
foreach ($this->new_images as $public_id){
    $item->images()->create([
         'public_id' => $public_id
    ]);
}

However in this case I missed the deleted Eloquent event on deleted images which is important in this case. I tried to delete them seperately:

$item->images->each(function($image){
    $image->delete();
});
foreach ($this->new_images as $public_id){
    $item->images()->create([
         'public_id' => $public_id
    ]);
}

And now the deleted event in fired however the old images are not removed from $item . They are actually deleted from DB but the $item is not updated (as it was in case of $item->images()->delete() ) and still holds references.

Is there a way to clear the relation? In pseudo-code:

//delete images one-by-one
$item->images = null;
// now add the new images

您可以使用以下方法重新加载图像数据：

$item->load('images');
